Myea Dark Lord possibly is easiest from OP classes to get now and some even loads quest for EDL after getting Dark Lord, Btw Easiest quite-op class to get now is Dragon Warrior, then u could try to get some like Wizard which can crit up to 70k, also Alchemist and Butcher,Dreadfiend if u have almost 4k rc's, Frostfiend of Kathleen which is quite considarable on PvP due its Stun,Dodge. For one-shot kills at Duels i also used classes like Bright Light Magician,Heroic Paladin,Lunar Raider, Doom Magi. If u have more then 7 days of Vip u can get Stalker class whitch will make enemy angry bcz its hiding skill xD.
